This lesion is a focal overgrowth of normal skeletal elements. In neurofollicular hamartoma, the histopathology shows a nodular dermal spindle cell proliferation surrounded by prominent sebaceous glands. The spindle cells are plump or wavy. The sebaceous proliferation surrounds the mesenchymal component (figures 1–3). The spindle cells are positive for S100, CD34 and Factor XIII. 85% are identified as solitary pulmonary nodules, 5%–15% are endobronchial. The lesion may be single or multiple and if large can result in respiratory embarass- ment by compression of lung tissue. A 44-year-old woman notes a lump in her left breast while taking a shower.
